Description
TECHNICAL FIELD

This invention relates to a medicament, particularly a novel 4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine derivative or a salt thereof useful as a therapeutic agent for central diabetes insipidus and nocturia, and a medicament which uses said compound as the active ingredient.

BACKGROUND OF THE INVENTION

Arginine vasopressin (AVP) is a peptide consisting of 9 amino acids which is biosynthesized and secreted in the hypothalamo-pituitary system. The receptor of AVP is classified into three subtypes V1a, V1b and V2, and a V1a receptor-mediated constriction action and a V2 receptor-mediated antidiuretic action are known as the main pharmacological actions of AVP in the peripheral system. As a V2 receptor-selective agonist, a peptide desmopressin (prepared by deleting amino group of the 1-position cysteine of AVP, and converting the 8-position arginine into d form) has been synthesized and used for the treatment of central diabetes insipidus (Non-patent Reference 1). However, since bioavailability of oral preparations of desmopressin is considerably low, a high dose is necessary for obtaining its effect. Thus, the desmopressin preparations are expensive, and generation of side effects based on the variation of absorption among individuals is observed in some cases. Accordingly, concern has been directed toward the development of a non-peptide antidiuretic agent which selectively stimulates V2 receptor and has high bioavailability.

On the other hand, accompanied by the diversification of medical treatment and advance of age, single use of a drug became rather rare, and in many cases, two or more drugs are administered simultaneously or intermittently. This is the same in the field of AVP receptor agonists. Drugs are inactivated and converted into metabolites by undergoing the action of drug metabolizing enzymes, and the most important among these drug metabolizing enzymes is cytochrome P450 (CYP). A large number of molecular species exists in CYP, and when two or more drugs which are metabolized by CYP of the same molecular species compete on the metabolizing enzyme, it is considered that they undergo a certain metabolic inhibition, though it varies depending on the affinity of the drugs for CYP. As a result, increase of blood concentration, prolongation of blood half-life and the like drug interactions are expressed.

Such drug interactions are undesirable actions except for the case in which they are used aiming at the additive action or synergistic action, because they sometimes cause unexpected side effects. Thus, concern has been directed toward the creation of a medicament which has a low affinity for CYP and a small possibility of causing drug interactions.

Up to now, tricyclic compounds represented by a general formula (A), a general formula (B) and a general formula (C) are known as non-peptide compounds which are V2 receptor-selective agonists and show antidiuretic action (Patent Reference 1, Patent Reference 2, Patent Reference 3).
(See said patent references for signs in the formulae.)

Also, a condensed azepine derivative represented by a general formula (D) is known as a V2 receptor-selective agonist (Patent Reference 4).
(See said patent reference for signs in the formula.)

In addition, benzazepine derivatives represented by a general formula (E) (Patent Reference 5, Patent Reference 6) and benzo-hetero ring compounds represented by a general formula (F) or a general formula (G) (Patent Reference 7, Patent Reference 8, Patent Reference 9) are known as V2 receptor-selective agonists.
(See said patent references for signs in the formulae.)

However, there is no description in any of these patent references regarding the 4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine derivative of the invention.

Also, though 4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine derivative having antagonism for the AVP receptor or oxytocin receptor are known, nothing is known about their relation to V2 receptor agonistic action, central diabetes insipidus and nocturia (Patent Reference 10, Patent Reference 11, Patent Reference 12). In this connection, Patent Reference 10 and Patent Reference 12 does not disclose the 4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine derivative of the invention in which CF3 or halogen is substituted to the 2-position benzoyl substituting on the 1-position of benzazepine. In addition, Patent Reference 11 discloses only a compound in which an aromatic ring is directly bonded to a heteroaryl group bonding to the carbonyl substituting on the 1-position of benzazepine, but does not disclose the 4,4-difluoro-1,2,3,4-tetrahydro-5H-1-benzazepine derivative of the invention in which the ring bonding to the carbonyl substituting on the 1-position of benzazepine has —O—, —S—, —NH— or a substituent group containing —N(lower alkyl)-.

Under such a situation, great concern has been directed toward the development of a non-peptide antidiuretic agent having high bioavailability, for the purpose of treating central diabetes insipidus and/or nocturia.

The same shall apply hereinafter.)

This production method is a method in which the compound (c) is produced by substituting leaving group Lv of the compound (a) by the compound (b), and then the compound (d) is produced therefrom by carrying out hydrolysis of the same as occasion demands.

(First Step)

Examples of the leaving group Lv in the compound (a) include fluoro, chloro, methanesulfonyloxy, p-toluenesulfonyloxy and trifluoromethanesulfonyloxy, of which fluoro, chloro and methanesulfonyloxy are preferred.

(First Step)

The compound (d) can be used in the reaction as free acid, but its reactive derivative can also be used in the reaction. Examples of the reactive derivative of compound (d) include methyl ester, ethyl ester, tert-butyl ester or the like general ester; acid chloride, acid bromide or the like acid halide; acid azide; active ester with N-hydroxybenzotriazole, p-nitrophenol, N-hydroxysuccinimide or the like; symmetric acid anhydride; mixed acid anhydride with alkyl carbonate halide or the like halocarboxylic acid alkyl ester, pivaloyl halide, p-toluenesulfonic acid chloride or the like; mixed acid anhydride such as a phosphoric acid system mixed acid anhydride obtained by reacting with diphenylphosphoryl chloride and N-methylmorpholine, and the like.

When the compound (d) is allowed to undergo the reaction as free acid, or an active ester is allowed to undergo the reaction without isolation, it is desirable to use a condensing agent such as dicyclohexylcarbodiimide (DCC), 1,1′-carbonylbis-1H-imidazole (CDI), diphenylphosphoryl azide (DPPA), diethylphosphoryl cyanide, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (WSCD) or the like.

According to the invention, an acid chloride method, a method in which the reaction is carried out in the coexistence of an active esterification agent and a condensing agent and a method in which a general ester is treated with amine are particularly convenient, because the compound of the invention can be obtained conveniently and easily.

Though it varies depending on the reactive derivative and condensing agent to be used, the reaction is carried out under cooling, under cooling to room temperature or under room temperature to heating, in a reaction inert solvent such as a halogenated hydrocarbon, an aromatic hydrocarbon, an ether, an ester, acetonitrile, DMF, DMSO or the like.

In this connection, it is advantageous in some cases in smoothly progressing the reaction to use the compound (1a) in an excess amount in carrying out the reaction, or to carry out the reaction in the presence of a base such as N-methylmorpholine, trimethylamine, triethylamine, diisopropylethylamine, N,N-dimethylaniline, pyridine, 4-(N,N-dimethylamino)pyridine, picoline, rutidine or the like. In addition, a salt consisting of pyridine hydrochloride, pyridine p-toluenesulfonate, N,N-dimethylaniline hydrochloride or the like weak base and a strong acid may be used. Pyridine can also be used as a solvent.

The reaction can be carried out in accordance with the method described in “Protective Groups in Organic Synthesis (3rd Edition)”.

Particularly, when benzyl group is used as the protecting group of hydroxyl group, a method in which benzyl group is removed by allowing pentamethylbenzene to react therewith in a strongly acidic solution such as trifluoroacetic acid or the like can also be used.

(Third Step)

As the leaving group Lv in the compound (2c), chloro, bromo, iodo, methanesulfonyloxy, p-toluenesulfonyloxy and trifluoromethanesulfonyloxy can for example be cited, of which bromo, methanesulfonyloxy and p-toluenesulfonyloxy are preferable.

Illustratively, oxidation of sulfur atom by metachloroperbenzoic acid or the like oxidizing agent, and the like can for example be cited, and such reactions carried out by employing or in accordance with the methods described in “Jikken Kagaku Koza (Experimental Chemistry Course) 4th edition” (Maruzen, 1990-1992). In addition, these steps which can be generally employed by those skilled in the art are not limited to the application to the compounds of the invention, and they can also be applied to the production intermediates. Illustratively, they can be applied, for example, to the compound obtained by the third step of the second production method, and thereafter, the next step can be carried out.

The compounds of the invention produced in this manner are isolated and purified as free compounds or salts thereof by carrying out salt formation treatment in the usual way. Isolation and purification are carried out by employing usual chemical operations such as extraction, concentration, evaporation, crystallization, filtration, recrystallization, various types of chromatography and the like.

Various isomers can be isolated in the usual way by making use of differences in physicochemical properties among isomers. For example, a racemic mixture can be converted into optically pure isomers, for example, by a general racemic body resolution method such as a method in which they are converted into diastereomer salts with tartaric acid or the like general optically active acid and then subjected to optical resolution. Also, a diastereomer mixture can be separated, for example, by fractional crystallization or various types of chromatography. In addition, an optically active compound can also be produced using an appropriate optically active material.

INDUSTRIAL APPLICABILITY

Accordingly, the compounds of the invention have antidiuretic action of a profile based on this action, and are effective in preventing and/or treating urinary frequency, urinary incontinence, enuresis, central diabetes insipidus, nocturia and nocturnal enuresis. Also, in addition to these, since they have the action to release blood coagulation factor VIII and von Willebrand factor based on the V2 receptor agonistic activity, they are useful for various bleeding conditions and useful in diagnosing, preventing and treating spontaneous hemorrhage, hemophilia, von Willebrand disease, uremia, congenital or acquired platelet dysfunction, traumatic and operation hemorrhage, hepatic cirrhosis and the like.

In addition, the compounds of the invention have markedly low inhibitory activity upon drug metabolizing enzymes CYP3A4 and CYP2C9, possibility of causing drug interaction with other drugs which are metabolized via CYP3A4 or CYP2C9 is small in comparison with the conventionally known benzazepine derivatives having arginine vasopressin V2 receptor agonistic activity, so that they are also excellent from the viewpoint that they can be safely used in the combined therapy with other medicaments.

A human V2 expression CHO cell membrane sample was prepared in accordance with the method of Tahara et al. (British Journal of Pharmacology, Vol. 125, pp. 1463-1470, 1998). A 2 μg portion of the membrane sample was incubated together with [3H]-arginine vasopressin (to be referred simply to as “[3H]-vasopressin” hereinafter) (0.5 nM, specific activity=75 Ci/mmol) and each compound to be tested (10−10 to 10−5 M) at 25° C. for 60 minutes in 250 μl in total volume of 50 mM Tris-HCl buffer (pH=7.4) containing 10 mM MgCl2 and 0.1% bovine serum albumin (BSA). Thereafter, free [3H]-vasopressin and receptor-bonded [3H]-vasopressin were separated using a cell harvester, and the receptor-bonded [3H]-vasopressin was adhered onto a uni-filter plate GF/B glass filter. After sufficient drying, this was mixed with a microplate scintillation cocktail, amount of the receptor-bonded [3H]-vasopressin was measured using top count and the inhibition ratio was calculated by the following formula.
Inhibition ratio (%)=100−(C1−B1)/(C0−B1)×100
C1: Amount of [3H]-vasopressin bonded to the membrane sample when [3H]-vasopressin and the receptor membrane sample are treated in the coexistence of test compound having known concentration

  • C0: Amount of [3H]-vasopressin bonded to the membrane sample when [3H]-vasopressin and the receptor membrane sample are treated in the absence of test compound
    B1: Amount of [3H]-vasopressin bonded to the membrane sample when [3H]-vasopressin and the receptor membrane sample are treated in the coexistence of excess amount of vasopressin (10−6 M)

Concentration of each test compound by which the inhibition ratio becomes 50% (IC50 value) was calculated by the aforementioned formula, and affinity of the test compound for the receptor, namely dissociation constant (Ki), was calculated from this by the following formula.
Dissociation constant (Ki)=IC50/(1+[L]/Kd)
[L]: Concentration of [3H]-vasopressin

Kd: Dissociation constant of [3H]-vasopressin against the receptor obtained by a saturation binding test

The compound of Example 3 was intravenously administered to group A at a dose of 0.3 mg/kg, and the compound of Example 9 to group B at a dose of 0.3 mg/kg, both after dissolving in a solvent (physiological saline containing DMSO), and the solvent alone at a dose of 1 ml/kg to group C as a control, and then 30 ml/kg of distilled water was orally administered by force 15 minutes thereafter (water loading). Urine samples until 2 hours after the water loading were collected using a metabolism cage, and the amount of urine when the water loading amount was defined as 100% was calculated as the urine excretion ratio. In this connection, average value of the urine excretion ratio until after 1 hour and the urine excretion ratio until after 2 hours in each group was used in the evaluation. The results are shown in Table 2.

As shown in Table 2, it was revealed that the compounds of the invention have excellent antidiuretic effects.

(3) Antidiuretic Test (Oral Administration)

Male Wistar rats (10 to 12 weeks of age) were used in the test. Each compound to be tested was orally administered, and then 30 ml/kg of distilled water was orally administered by force 15 minutes thereafter (water loading). Urine samples until 4 hours after the water loading were collected using a metabolism cage, and the amount of urine when the water loading amount was defined as 100% was calculated as the urine excretion ratio. In this connection, the dose each test compound necessary for reducing 50% of the urine excretion ratio (ED50) was used in the evaluation.
